A new method for simulating polarimetric scattering on the rough sea surface is studied based on the matrix of the Kirchhoff scattering facet. A two-dimensional sea surface is described as a height matrix and two slope matrices in the x and y direction, an expression for the scattered field with the elliptic polarized incidence wave is calculated in the Cartesian coordinate system by Kirchhoff approximation and the model of fully polarized RCS is obtained. Finally the fully polarized backscattering RCS and polarization signatures of the fractal sea surface are simulated for different conditions and the results are in accord with the characteristics of sea surface scattering. This method can be applied to many sea surface models because it uses discrete analysis on the two-dimensional model, which is important for the retrievement of sea polarimetric information.

Key words: polarimetric scattering, fractal sea surface, wind speed, polarization signatures
